20 Fretp Museum or NATURAL History — Zoo.ocy, Vou. X. 
Characters. Allied to Crocidura argentata fischeri, with which it 
agrees in the general color of the upperparts, but tail decidedly longer 
and more extensively dusky on the upper side. Upperparts in fresh 
pelage fawn color with a fine vermiculation of lighter (almost ecru 
drab); underparts and upper lip dull grayish white, the bases of the 
hairs mouse gray to smoke gray; feet white; tail above broadly dusky 
brownish, below whitish for proximal two-thirds, mixed dusky and 
whitish for terminal third. Skull similar to that of fischeri but smaller 
and with a more compressed rostrum and decidedly smaller teeth; 
second unicuspid very slightly smaller than third. : 
Measurements. Type: Total length 150; head and body go; 
tail vertebre 60; hind foot 15. Skull of type: Condylo-incisive 
length 22; length of toothrow 9.6; maxillary width 6.8; greatest 
width of m!' 2.3. 
Remarks. The few differences between this species and C. a. fischeri 
are so pronounced that it is not possible at present to include it with 
that form as a subspecies of argentata. The difference in the size of 
the teeth is quite decided and there is no indication of gradation. 
The color, however, is about as in fischeri except that the tail is darker: 
Crocidura allex sp. nov. 
Type from Naivasha, British East Africa. No. 16820 Field 
Museum of Natural History. Adult male. Collected January 31, 
1906, by E. Heller. 
Characters. Allied to C. bottegi and possibly to C. cunninghamet; 
size larger than in bottegi with larger skull and teeth; color lighter 
especially on underparts and feet; size somewhat smaller than in 
cunninghamei; skull shorter with a higher, more vaulted braincase; 
teeth smaller. Upperparts'dull brown; underparts buffy gray; feet 
grayish, practically same color as underparts; pelage longer and 
coarser than in cunninghamet. 
Measurements. Type: Total length 109; head and body 64; tail 
vertebre 45; hind foot 12. Skull: Greatest length 17.1; greatest 
breadth 7.7; maxillary breadth 5.2; postpalatal length 7.9; toothrow 
7.15; greatest width m' 1.7. 
Remarks. The shape of the skull in this species is more like that of 
bottegi than that of cunninghamei and its teeth though larger are more 
like those of bolttegi. C. cunninghamei has a longer, narrower skull 
and a flatter braincase, and its teeth are scarcely smaller than in small 
specimens of hildegardeae,
